The CAPS deploys from its cubbyhole behind the bulkhead at the rear of the baggage compartment. It fires out the top of the fuselage, aft of the rear window. The hatch that is blown out when the rocket fires is not visible, since it is painted over.
Besides avoiding the rocket, rescue workers should also avoid cutting or snagging the CAPS cable, since this could cause accidental activation. The CAPS cable runs from a handle in the roof over the front seats, through the roof, to one side of the rear window, and down to the rocket.
If the plane is upright, the rescuers could first attempt to open either door by pushing in on the door handle at the center to lever out the handle end, then grabbing the handle end and turning it in the direction marked “OPEN”.
If the doors do not open, or if the plane is not upright, the windows on the door can be broken out by striking them with a hammer or axe ner the edge. There is a placard on the window noting this.
An occupant can be unbelted from his four point harness by releasing the conventional seatbelt buckle in the center of his waist.
The easiest way to remove rear seat occupants is by tilting the front seatbacks forward. There is a lever on the left and right side of each front seat that releases the seatback lock.
